New Facebook plugin shows readers other stories 'liked' by their friends

Facebook released a new website plugin today that shows readers related articles that their friends have "liked" on the same site. The "recommendations bar" sits at the bottom-right of the browser and expands to show a couple of recommended stories as a reader scrolls through an article.

Facebook already has a "recommendations box," an embeddable widget, that served a similar function. But the company says the new bar that floats on top of the page is getting three times more clickthroughs than the widget.
